FUEL-CONTROLLING DEVICE FOR MOTORS.

Applieation 'filed September 7, 1923 Serial No. 661,471.

To all whom it may concern: 1

Be it known that ADOLF B. HROMAS, a citizen of the United States, residing at Ulysses Nebraska,has invented new and useful Imp fovements in Fuel-Controlling Devices for otors, of which the following is a specification.

In a fuel controllin device for internal combustion motors, it is the purpose of the present invention to provide means for permitting-an auxiliary supply of air to enter the gasoline tank to be carried to a point a substantial distance below the level of the gasoline and then conducted to the crank case and thence to the carbureter, additionally volatilizing the charge and hence producing a better fuel for combustion in the combustion chamber of the motor, thereby saving fuel, and enabling the chauffeur to operate the automobile a greater distance on a predetermined amount of gasoline than heretofore obtained.

Another purpose is to provide means for conducting the air from the tank in such wise as to gather the waste that may pass around the piston and enter the crank case and conduct it into the carbureter, thereby producing a superior charge of fuel for combustion.

Still another purpose is to provide means for carrying the air from the crank case without interfering with the passage of oil into the crank case, that is, when a supply of oil is necessary.

It is to be understood that the particulars herein iven are in no way limitative and that, w ile still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to the circumstances.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view showing the improved fuel controlling device as applied for use in connection with internal combustion motors.

Figure 2 is a sectional View through the gasoline tank, showing the means for permitting air to enter the tank and be conin the county of Butler and State of ducted to a point below the level of the gasoline and also showing the outlet for the air.

Figure 3 is a sectional View through the crank case, showin the means whereby the air and the fumes rom the gasoline may be carried ofi from the crank case to the carbureter. K

Figure 4 is a view at ri hta'njgles to Figure 3 on line 4-4 thereo Referring to the drawings, 1 designates a conventional form of internal combustion motor, 2 denotes a conventional form of carbureter, 3 the tank andA'the crank case. A cap 5 provided with a threaded extension 6 and an adjacent shoulder 7 is provided and is adapted to connect with thegasoli'ne tank by engaging the extension 6 with the threads in the opening of the tank.

The cap includes a second extension 8 which is reduced and which extends into the tank and terminates at a point a substantial distance below the level of the gasoline, whereby a supply of air entering the lateral extension tube 9 may be conducted to a point below the level of the gasoline and closely adjacent the bottom of the tank so that it may again ascend through the body of gasoline and pass out through the cap 10 which also has a lateral extension tube 11.

The cap 10 has a threaded extension 12 and is provided with an annular shoulder 13. The extension 12 is threaded into the gasoline tank adjacent the end opposite the end having the cap 5. However, prior to disposing the caps 5 and 10 in position with their extensions 6 and 12 in threaded engagement with the openings in the wall of the tank, suitable gaskets or washers 14 and 15 are first placed in surrounding positions with respect to the the extensions 6 and 12 so that the shoulders 7 and 13 will bear upon the gaskets and insure a tight fitting joint between the extensions 6 and 12 and the edges of the openings as well as precluding the escape of any air about the shoulders 7 and 13.

The lateral extension tube 11 is connected to a suitable metal flexible tube 16 which, in turn, connects to a tube 17 which is carried by a plate 18 which is mounted upon the transmissionv case. This plate 18 supports the tube 17 in such wise as to hold it in position whereby it may connect with the i,eia,eri

crank case through the medium of a second metallic flexible tube 19. The flexible metallic tube 19 is communicably connected with the crank case for the purpose of conducting the supply of air (which percolates through the body of gasoline in the tank) to the crank case.

An outlet air cup or tube 20 is engaged with one of the oil holes of the crank case, there being a bolt 21 having a hook 22 at one end for holding the outlet cup in posi-' tion. The upper .end of the outlet cup has a lid or cover 23 for closing the cup to prevent dirt and other foreign matter from entering the cup when filling the crank case with oil. A tubular extension 24 is provided. This extension 24 engages through the wall of the outlet cup 20 and is brazed thereto, as at 25. It will be noted that the end portion of the lateral extension 24 is fitted transversely of the cup and has its lower portion cut away to permit the air passing upwardly through the outlet cup to pass out through the extension 24:.

It will be noted that the part of the extension tube 24 opposite the cut away portion 26 deflects the oil toward either side when the cup is in the act of receiving oil, conducting it to the crankcase. The belt 21 engages through the wall of the extension tube 24; and is supplied with a nut 27 for adjusting the bolt in its proper position to retain the cup in the oil hole. The extension tube 24 connects with an elbow 28 by means of a metallic flexible tube 29, said elbow being, in turn, properly and suitably connected to the carbureter. v

In the opera-tion of gasoline motors, it is well knownthat there is a certain percentage of waste about the pistons during their operating-- movements and it is also well known that an auxiliary supply of air supplied with fumes from gasoline will act to additionally volatilize a charge and thereby save fuel and permit the vehicle to travel a greater distance on a predetermined supply of gasoline than has been heretofore obtained. Hence in the present device the air is conducted through the body of the gaso line, gathering the fumes therefrom and using the mixture for conduction into the carbureter.

The connections between the gasoline tank and the carburetor, as above described, are designed to be air-tight in order to prevent any escape of the mixture which passes through the connections.

The invention havingbeen set forth, what is claimed is:

1. In a fuel controlling device for internal combustion motors, the combination with the crank ease including a cup mounted in one of the oil holes whereby oil may be poured into the crank case, of a gasoline tank, means for conducting air-below the level of the gasoline in the tank whereby it may percolate through the body of gasoline, means for conducting the mixture of air and fumes from the gasoline to the crank case,

means connecting the cup and the carbureter for carrying the mixture of air, fumes from the gasoline and fumes from the oil from the crank case to the carbureter, and means extending into the cup for deflehting the oil to either side when poured through the cup, thereby preventin the oil from entering the connection from t e carburetor where it ex- .tends into the cup.

2. In a fuel controlling device for internal combustion motors, the combination with the crank case thereof having an oil hole or opening therein for the application of oil to the case, and a carburetor, of a fuel connection between the carburetor and the crank case, said connection com risinga cup seated in the oil hole, a removable cover closing the cup at the top, a tubular member eliieeting communication between the cup and the carhuretor and extending laterally through the side walls of the cup and being cut away within the cup below the plane of the hornzontal diameter, and a clamping bolt engaging the extension within the cup and serv- Iihlng to clamp the latter in place in the oil In testimony whereor .he alilxes his signature.
